Mam aplikację, która rejestruje się w GCM dla powiadomień push. Ten kod działa dobrze i nie jest źródłem mojego problemu. Po zarejestrowaniu aplikacja po prostu wyświetla stronę internetową w WebView. Jak dotąd wszystko dobrze działa, jeśli karta sieciowa urządzenia jest włączona.

Jeśli karta sieciowa jest wyłączona, przeglądarka internetowa powinna ładować się z pamięci podręcznej. Ta część nie działa. Po zapoznaniu się z poniższym samouczkiem pobrałem z niego części, aby zapisać strony w pamięci podręcznej zapisanej na karcie SD.

Jeśli uruchomię aplikację, zostanie wyświetlona strona internetowa. Jeśli następnie wyłączę kartę sieciową i odwiedzę witrynę, nie będzie ona wyświetlana. Sprawdzam katalog pamięci podręcznej na karcie SD i części strony zostały zapisane w pamięci podręcznej.

Dlaczego witryna nie ładuje się z pamięci podręcznej w trybie offline?

Czy możliwe jest przechowywanie stron internetowych w pamięci podręcznej, dopóki aplikacja nie zostanie odinstalowana lub Android nie zdecyduje inaczej?

seminarium

Samouczek pokazuje, jak utworzyć katalog na sdcard i napisać do niego. Katalogi istnieją, ale widok sieci Web nie jest przywracany z tej pamięci podręcznej w trybie offline.

poniżej jest to, jak nazywam działanie główne, które wyświetla widok internetowy.

Intent i = new Intent(getApplicationContext(), MainActivity.class);
                //i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                i.putExtra("name", "hardcoded client name");
                i.putExtra("email", "hardcoded email");
                startActivity(i);
                finish();

.

Oto pełna MainActivity. Możesz zignorować pierwszą część, ponieważ jest to kod, który obsługuje elementy powiadomień wypychanych GCM, które działają. Muszę wiedzieć, dlaczego przeglądarka internetowa nie będzie ładowana z pamięci podręcznej.

To jest logowanie po wyłączeniu karty sieciowej.

Jedną z rzeczy, które zauważyłem, może być nic, ale aktywność rejestracyjna to działanie, które wywołuje MainActivity. RegisterActivity ma tylko przycisk, który uruchamia Intent for MainActivity. Po wyłączeniu karty sieciowej muszę nacisnąć przycisk na registerAcivity, który wywołuje Cateate w MainActivity. To jest jak nowa instancja MainActivity ?? Czy może to mieć wpływ na buforowanie widoku internetowego. W efekcie onDestroy głównej działalności musiał zostać wywołany po drodze.

Również inna rzecz przykuła moją uwagę.
